Balancing Valve

HYDROCONTROL VTR VFC VFR VFN

 

Introduction

Oventrop double regulating and commissionig valves “Hydrocontrol VTR/VFC/VFR/VFN’’ are installed in hot water central heating and cooling systems and serve to achieve a hydronic balance between the various circuits of the system.
The double regulating and commissioning valves may be installed in either the supply or the return pipe.

  • The location of functioning components on one level allows a simple assembly and easy operation
  • Only one valve for 5 functions:
    1. Presetting
    2. measuring
    3. isolating
    4. filling
    5. draining
  • Low pressure loss (oblique pattern)
  • Infinitely adjustable presetting which can be read of in any position due to the moveable display, exact measurement of pressure loss and flow by using the pressure test points
  • Fill and drain ball valve with internal stop and pressure test point with O-ring seal between valve body and test point(no additional seals required)
  • Patented measuring channel led around the stem assembly to the test points ensures the best possible accuracy between the differential pressure measured at the pressure test points and the actual differential pressure of the valve.
